And of course if there are things that may apply to you particularly.
E.g. schools differ in the way they deal with bilingual/multilingual children (some only pay attention to them if they fall behind in English, others recognise that multilingual children have specific challenges even if they are great at English and provide targeted support). This is something you can ask about.
And schools differ in the way they use Pupil Premium money, and hence it can make a difference how likely it is that your child will actually benefit from it. There is statutory information regarding Pupil Premium so you should be able to look that up.
Some schools are Infant schools so go only to Y2, in which case you may be looking at which Junior schools they tend to feed into, what exactly the admission criteria are for the Junior schools, how well they coordinate with each other (you may well end up having a child at the Junior and Infant at the same time, so it's important that pick-up/drop off works), and how they organise the transition from infants to juniors.
You may want to look ahead at which Secondary schools there are in your area and how you get into them; e.g. if you need to be in a certain feeder school.
You may be interested in knowing what role faith plays in each school. Some non-faith schools do more religious stuff than some faith schools. E.g. frequency of prayers, singing hymns, etc.
But at the end of the day, for us for DC1 it was all about the 'feeling' we got, in conjunction with practical/pragmatic considerations.
I just couldn't make myself like our nearest school, and some things rubbed me up the wrong way there (observed a couple of reception children sitting alone at a table (each separately) doing nothing at all. Literally staring into space. For the whole duration of our visit.)
The second nearest school was lovely in many ways but there was a lot of shouting and swearing and even fighting (parents) to be overheard at pick-up time.
The school that we liked best, with a margin, was too far away to justify choosing it over our second favourite, which we liked far less but deemed 'good enough', and within walking distance.
Now in the process of choosing for DC2, trying to figure out if there is anything that might justify choosing to send them to two different schools. DC2 has very different needs to DC1 so it is not obvious that we'd choose the same school if DC2 were our first, but again if it is 'good enough' then can we justify the organisational nightmare of having them in two different schools?
